| 英文摘要 | Using a sample of (225.2 +/- 2.8) x 10(6) J/psi events collected with the Beijing Spectrometer at the Beijing Electron-Positron Collider, CP and P violating decays of eta, eta', and eta(c) into pi(+)pi(-) and pi(0)pi(0) are searched for in J/psi radiative decays. No significant eta, eta', or eta(c) signal is observed, and 90% confidence level upper limits of B(eta -> pi(+)pi(-)) < 3.9 x 10(-4), B(eta' -> pi(+)pi(-)) < 5.5 x 10(-5), B(eta(c) -> pi(+)pi(-)) < 1.3 x 10(-4), B(eta -> pi(+)pi(-)) < 6.9 x 10(-4), B(eta' -> pi(0)pi(0)) < 4.5 x 10(-4), and B(eta(c) -> pi(0)pi(0)) < 4.2 x 10(-5) are obtained. |
